Answer:
a) (62 +68)/545
b) The two genes are linked.
Explanation:
a) The recombination frequency is equal to:
[tex]Re_{fr} =\frac{number-of-recombinant-offspring}{total-number-of-offspring} *100=\frac{68+62}{545} *100=23.85[/tex]%
b) It can be seen that red plants with single flower and yellow with double flower are recombinant, this means that their parental combinations are uneven. This is due to a cross that occurred between the two genes. From the obtained result it can be said that both genes are linked.
